Yes, Snow White appears at Germany in Epcot--usually beginning the the early afternoon. In the AM, she appears at the Princess breakfast in Norway.
Sw is usually at the breakfast in Cinderella Castle. Sometimes you can find her at MK near the Skyway. She is in the afternoon parade at the MK--she stands on the rear of the Pinocchio float. The 7 Dwarfs walk alongside the float. She is also in the evening Spectromagic parade--she walks along the sidewalk greeting guests--stand on the Emporium side of Main Street to see her. Snow White also appears in the Cinderella's Surprise Celebration Castle Show.
Hope this helps.
